Description
BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a telescopic scraper tool and more particularly pertains to providing an adjustable handle that can increase and decrease the reach of a scrapper blade and is further capable of accommodating scraper blades of various widths.

2. Description of the Prior Art

The use of a scrapper tool is known in the prior art. More specifically, a scrapper tool heretofore devised and utilized for the purpose of scrapping surfaces is known to consist basically of familiar, expected, and obvious structural configurations, notwithstanding the myriad of designs encompassed by the crowded prior art which has been developed for the fulfillment of countless objectives and requirements.

By way of example, U.S. Pat. No. 5,337,442 to Stewart discloses a scrapper apparatus. U.S. Pat. No. 5,165,144 to Nisenbaum discloses a tool handle and angularly adjustable attachment. U.S. Pat. No. 4,517,700 to Pinto discloses an adjustable scrapper tool. U.S. Pat. No. 3,562,826 to Vaughn discloses a multiple purpose scrapping tool. Lastly, U.S. Pat. No. 338,822 to Mallaliem discloses a scrapper handle.

While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not describe telescopic scraper tool that allows a user to reduce back strain through the use of the tool when the height of the scrapper is adjusted by sliding the first handle up and down within the second handle and locking the handles in position with the scrapper blade attached thereto.

In this respect, the telescopic scraper tool according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in doing so provides an apparatus primarily developed for the purpose of providing an adjustable handle that can increase an decrease the reach of a scrapper blade and is further capable of accommodating scraper blades of various widths.

Therefore, it can be appreciated that there exists a continuing need for a new and improved telescopic scraper tool which can be used for providing an adjustable handle that can increase an decrease the reach of a scrapper blade and is further capable of accommodating scraper blades of various widths. In this regard, the present invention substantially fulfills this need.

DESCRIPTION OF THE PREFERRED EMBODIMENT

With reference now to the drawings, and in particular to FIG. 1 thereof, the preferred embodiment of the new and improved telescopic scraper tool embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described.

The present invention, the telescopic scraper tool 10 is comprised of a plurality of components. Such components in their broadest context include a first handle, a second handle, a nut, and a scrapper component. Such components are individually configured and correlated with respect to each other so as to attain the desired objective.

Specifically, the present invention includes a first cylindrical handle 12 that has a first upper end 14 with a threaded projection 16 and a first lower end 18. The threaded projection has a diameter of five-eight inch. The first handle has a diameter of one inch and a length of about twenty-four inches. The length of the first handle includes the threaded projection. The threaded projection is cylindrical in shape and has a length of about of 6.5 percent of the length of the handle. The handle of FIG. 1 is formed of metal, plastic, or wood. The projection is integral the first handle and formed of an identical material. The preferred material is metal because of its durability and strength.

As illustrated in FIG. 2, a second cylindrical handle 22 is provided. The second handle has a second upper end 24 that is threaded and has a rounded second end 26 that is closed. The second upper end has an aperture therein. The aperture extends to the second rounded end. The second handle has a diameter of about one and one-fourth inch for slidable receipt of the first handle 12 therein. The second handle has a length of about twenty-three and one-fourth inches. The second cylindrical handle is capable of receiving ninety-five percent of the length of the first handle to form a telescopic handle 30. As shown in FIG. 3, the telescopic handle has an increasing and decreasing length of about between two to four feet. The second handle is formed of the same material that is used to form the first handle.

Additionally, a cylindrical coupling nut 34 is provided. The nut has a top end 36 and a bottom end 38 with an exterior surface area 40 therebetween. The coupling nut is formed of metal. The top end has an overhang 42 for capturing of a ring 44 therein. The ring is formed of a rigid plastic. The surface area has a plurality of rectangular raised portions 48 covering a circumference of the surface area. The raised portions are capable of increasing the gripping friction between fingers and the nut. Increased friction allows the user to rotate the coupling nut clockwise and counter-clockwise for placement and removal. The nut is capable of slidable receipt of the first handle 12 therethrough. As best illustrated in FIG. 4, the nut is capable of threadable coupling with the second upper end 24 of the second handle 22 when the first handle 12 is positioned within the second handle. Also, as shown in FIG. 4, the second upper end rests upon the ring 44 of the nut when the first handle is positioned therein. The nut locks the two handles when the telescopic handle is formed and maintains the position of the telescopic handle.

Furthermore, a scrapper component 52 is provided. As shown in the Figures, the scrapper component resides along an axis defined by the handles. The scraper component has a cylindrical support handle 54 with a triangular portion 56 that has a blade edge 58. The scraper component has a length of about eight inches, with the triangular portion being sixty percent of the length. The triangular portion has a blade width between two to five inches as shown in FIG. 5. The triangular portion is formed of metal with the blade edge being tapered. The tapering of the blade's edge improves the blade's scrapping ability. The blade edge is rigid for scraping a surface above the arm reach of a user and for scrapping a surface below the arm reach of the user. Increasing the reach height of the scrapper by using the telescopic handle will reduce strain to the back of the user. Reduced back strain allows the user to work longer hours.

Lastly, the support handle 54 has a decreasing exterior diameter decreasing from a back end 60 to the triangular portion. The support handle has an internal threaded portion 62. The support handle has a length of about two inches with an internal threaded portion capable of threadable coupling with the threaded projection 16 of the first upper end 14 of the first handle 12. The support handle is coupled to the first handle when the first handle is secured within the second handle 22 by the coupling nut 34.

The present invention is a telescopic scraper tool that has a first handle and a second handle that is capable of receiving the first handle therein. The telescopic handle is formed when the handles are coupled together and locked in place by a coupling nut. At the end of the first handle has a scrapper component. The scrapper component has a blade edge for scraping. The telescopic scrapping tool can be adjusted to various heights ranging from two feet to four feet. The scrapper tool can be used by user when scrapping overhead or when scrapping near the feet of the user. With the scrapper tool the user is able to set the length of the handle according to his or her needs. The scrapper may also be used without the handle if necessary. The telescopic scrapper tool will make it easier for a worker to scrap paint, plaster walls and scrap wood floors, without bending and reaching. Additionally, by using the telescopic scrapper the user will not have to use a stepladder that may cause additional undue stress to the lower back muscles, and other muscles. Generally, the telescopic scrapper makes it easy for the user to reach hard places.

As to the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided.

With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.

Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
